Regular -measures are not always Gibbsian
Roberto Fernández, Sandro Gallo, Grégory Maillard
Regular -measures are discrete-time processes determined by conditional expectations with respect to the past. One-dimensional Gibbs measures, on the other hand, are fields dete…
A large-deviation view on dynamical Gibbs-non-Gibbs transitions
Aernout van Enter, Roberto Fernández, Frank den Hollander +1
We develop a space-time large-deviation point of view on Gibbs-non-Gibbs transitions in spin systems subject to a stochastic spin-flip dynamics. Using the general theory for large…
Decay of correlations for non Hölderian dynamics. A coupling approach
Xavier Bressaud, Roberto Fernández, Antonio Galves
We present an upper bound on the mixing rate of the equilibrium state of a dynamical systems defined by the one-sided shift and a non Hölder potential of summable variations. The b…
Loss network representation of Peierls contours
Roberto Fernández, Pablo A. Ferrari, Nancy L. Garcia
We present a probabilistic approach for the study of systems with exclusions, in the regime traditionally studied via cluster-expansion methods. In this paper we focus on its appli…
Measures on contour, polymer or animal models. A probabilistic approach
Roberto Fernández, Pablo A. Ferrari, Nancy L. Garcia
We present a new approach to study measures on ensembles of contours, polymers or other objects interacting by some sort of exclusion condition. For concreteness we develop it here…
